Features
Benefits
8-bit HCS08 Central Processor Unit (CPU)
⢠Up to 20 MHz HCS08 (10 MHz internal bus
frequency)
⢠Offers high performance up to 5V, ideal for industrial
applications
⢠HC08 instruction set with added BGND instruction
⢠Enables backward object-code compatibility with
68HC08 and 68HC05
⢠Allows existing code libraries to be used
⢠Allows for efficient, compact module coding in
assembly or C complier
⢠Supports up to 32 interrupt/reset sources
⢠Enables software flexibility and optimization for real-
time applications
Integrated Third-Generation Flash Memory and RAM
⢠Embedded flash that is in-application
reprogrammable over the full operating voltage and
temperature range with a single power supply
⢠Provides users a single solution for multiple platforms
or a single platform that is field reprogrammable in
virtually any environment
⢠Does not require additional pin or power supply for
flash programming, thus simplifying the interface for
in-line programming and allowing for more GPIO pins
⢠Extremely fast, byte-writable programming;
as fast as 20 µs (burst mode)
⢠Helps reduce production programming costs through
ultra-fast programming, as well as lowering system
power consumption due to shorter writes
⢠Up to 100,000 write/erase cycles at typical voltage ⢠Allows electrically erasable programmable read-only
and temperature (10k minimum write/erase); 100
memory (EEPROM) emulation, reducing system costs
years typical data retention (15 years minimum)
and board real estate
Flexible Clock Options
⢠Internal clock source (ICS) module with a
frequency-locked loop (FLL) controlled by internal
or external reference
⢠Eliminates the cost of utilizing external clock
components, reducing board space and increasing
system reliability
⢠Precision trimming of internal reference allows
typical 0.2 percent resolution and 2 percent
deviation over operating temperature and voltage
⢠Provides one of the most accurate and cost-effective
internal clock sources in the market
⢠Internal reference can be trimmed from 31.25 kHz ⢠Enables adjustment of bus clocks for optimal serial
to 38.4 kHz, allowing for up to 10 MHz FLL output
communication baud rates and/or timer intervals
⢠Low-power oscillator module (XOSC) with
software-selectable crystal or ceramic resonator
range, 31.25 kHz to 38.4 kHz or 1 MHz to 16 MHz
⢠32 kHz oscillator provides low-power option
for systems requiring time-keeping functionality
(i.e. time and date) while in low-power modes
22 I/O Pins, One Input-Only Pin and One Output-Only Pin
⢠Outputs 10 mA each; 60 mA max for package
⢠High-current I/O allows direct drive of LED and other
circuits, virtually eliminating external drivers and
reducing system costs
⢠Software-selectable pull-ups on ports when used
as inputs; internal pull-up on reset and interrupt
request (IRQ) pin
⢠Reduces customerâs system cost by eliminating the
need for external resistors
⢠Software-selectable slew rate control and drive
strength on ports when used as output
⢠Allows user to configure ports for slower slew rate and
weaker drive to minimize noise emissions from the MCU
⢠8-pin keyboard interrupt module with software-
selectable polarity on edge or edge/level modes
⢠Keyboard scan with programmable pull-ups/pull-downs
virtually eliminates external glue logic when interfacing
to simple keypads
